Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the back-up power source is integrated into the controller module, then the reliability of the controller is improved, but the ease of replacement and adaptability deteriorate

Engineering Contradiction:
ImprovereliabilityVSAvoidadaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The back-up power source is separated from the main controller module and placed in a removable energy storage module. This segmentation allows the power source to be easily replaced or swapped between different controller modules without affecting the controller's reliability, thus resolving the contradiction between integrated reliability and replaceability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The removable energy storage module can be used with multiple different controller modules, providing universal applicability. This allows the same power source to serve multiple functions across different devices, improving adaptability while maintaining the reliability benefits of a dedicated power source.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If the back-up power source is integrated into the controller module, then the reliability is improved, but the ease of operation and replacement time deteriorate

Engineering Contradiction:
ImprovereliabilityVSAvoidease of replacement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By dividing the system into a removable energy storage module and a main controller module, the power source can be easily accessed, removed, and replaced without disassembling the controller. This segmentation directly improves ease of replacement while the modular design ensures the power source remains reliably integrated when attached.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The back-up power source is extracted from the permanent integrated position and placed in a removable module that can be easily taken out and replaced. This extraction allows for simple replacement operations while the module can be reattached to restore full functionality, maintaining reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Quantity of substance

If a battery is used as the back-up power source, then the energy storage capacity is improved, but the adaptability to different environments deteriorates

Engineering Contradiction:
Improveenergy storage capacityVSAvoidenvironmental adaptability
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The removable energy storage module can accommodate different types of power sources (batteries, capacitors) and be used across multiple controller modules and environments. This universality allows the system to adapt to different environmental requirements while maintaining sufficient energy storage capacity through appropriate power source selection.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system allows dynamic selection and replacement of different energy storage technologies based on environmental conditions. Users can switch between battery-based and capacitor-based solutions depending on temperature, safety requirements, or application needs, thus improving environmental adaptability while maintaining energy storage capacity.

Inventive Principle:
Principle #15Dynamics

4Object-affected harmful factors

If the controller must be powered down for battery replacement, then the safety is improved, but the loss of time increases

Engineering Contradiction:
ImprovesafetyVSAvoiddowntime
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The removable energy storage module allows battery replacement without requiring the controller to be powered down. The modular design enables safe replacement operations to continue while the controller remains operational, eliminating downtime while maintaining safety through proper isolation procedures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller can continue operating while the battery is being replaced in the removable module. This continuity of useful action eliminates the need to power down the controller during maintenance, reducing downtime while safety protocols are maintained through proper electrical isolation during the replacement process.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

An industrial automation controller module includes a main module and an energy storage module (ESM) releasably connected to the main module. The ESM includes a back-up electrical power source such as a battery or a capacitor that is electrically connected to processor circuitry of the main module when the ESM is physically connected to the main module. In case of interruption of operating power to the processor circuitry of the main module, the back-up power source of the ESM supplies back-up power to the main module to allow for completion of an emergency save operation to save data to non-volatile memory in the main module. If the ESM includes a capacitor back-up power source, it is charged by the main module and the capacitor charge is dissipated if the ESM is separated from the main module. In all cases, the ESM can include one or more configuration parameters stored therein that allow the main module to validate (or not) the ESM for the requirements of the main module, with respect to type of back-up power source, product code or model, capacity of back-up power source, and the like. The main module can also initiate periodic testing of the back-up power source of the ESM.
